Patented May 11, 1937 UNITED STATES PATENT OFFICE 2,080,264 SHOWER HEADLeo E. Gray, San Pedro, Calif. Application February 3, 1936 Serial No.62,150 3 Claims. (01; 299-419) This invention relates to shower heads.The general object of the invention is to provide a shower head whichcan be economically manufactured and which can be operated effectivelywith a minimum amount of water.

A more specific object of the invention is to provide a shower headincluding a body and a cap member so constructed and arranged thateither control of the fluid or of thespraying effect may be secured.

A further object of the invention is to provide a shower head soarranged that the water passes in a novel manner through and from theshower head. l

Other objects and the advantages of my invention will be apparent fromthe following description taken in connection with the accompanyingdrawing, wherein:

Fig. 1 is a side elevation showing my improved shower head;

Fig. 2 is a top plan view of the head; i

Fig. 3 is a central section taken on line 3-3 of Fig. 1;

Fig. 4 is a bottom plan view of the inner member of the head.

Referring to the drawing by reference characters I have shown myinvention as embodied in a shower head which is indicated generally atIU. As shown the shower head comprises a body H having a cap member 12thereon.

The body ll includes an upper portion which is internally threaded as atH to receive a supply pipe I 4 by means of which water may be directedinto the head. The exterior of the body adjacent the threads 13 ishexagonal as at l5 to receive a wrench. The intermediate portion of thebody is provided with a central bore I 6 and with an external threadedportion I1, while the lower portion of the body is substantiallycylindrical and of less diameter than the threaded portion H. The lowerportion isprovided with a plurality of intersecting apertures I8 whichcommunicate with the central bore IS.

The lower end of the body is bevelled as at I9 and is provided with acentral cylindrical recess 20 with the wall 2| defining the recessprovided with a plurality of slots 22. These slots are directedtangentially with the outer wall of the slots substantially tangent tothe cylindrical recess 20.

The cap member comprises an upper portion 23 which receives the upperportion ll of the body. A gasket 24 is shown as engaging a shoulder 25on the body. This gasket is U-shaped in cross-section so that any fluidentering the gasket cavity will press the outer portion of the gasketoutwardly and the inner portion inwardly, thus efiecting a tight seal.

The intermediate portion of the cap is threaded as at 26 to receive thethreads IT on the body and the lower end of the cap is shown asfrustoconical in shape and is provided with a discharge aperture 21which communicates with a flaring bore 28 and the latter communicateswith a flaring wall 29 which is arranged at a bevel corresponding to thebevel 19 on the body I I. a m

The upper surface of the cap I2 is provided with a projecting lug 30while the body is provided with an aperture 3| which is threaded toreceive a screw 32. This screw projects below the hexagonal portion l5when fully screwed in 15 position so that when the screw is fullyinserted rotation of the cap is limited to less than a completerevolution thereby preventing unauthorized removal of the cap.

In use the device is installed as shown and the cap is rotated until thebevel IS on the body is engaged by the bevelled portion 29 of the cap.The screw32 is then turned to position and the shower head is adjustedby backing off the cap until the correct spraying effect is secured.

The water passes from the pipe l4 through the bore 26 then through theapertures l8 and around the lower portion of the body whence it passesinwardly through the slots 22 into the recess 20 thus imparting a rotaryaction to the sprayed water. The water then passes through the flaredportion 28 out of the aperture 21. As the cap is backed away from thebody more of the water is free to pass around the lower end of the bodyso that this water is added to the stream passing 35 through theapertures 22 so that in this manner the spray can be adjusted. Theamount of water passing through the shower head may be controlled bysuitable valve means on the pipe l4.

From the foregoing description it will be ap- 40 parent that I haveprovided a novel shower head which can be economically manufactured andwhich is highly efiicient in use.

Having thus described my invention I claim:

1. A shower head comprising a body having a 5 cylindrical portion at oneend of said body including an intermediate portion with a bore thereinadapted to communicate with a pipe, the outer wallof said intermediateportion being of less diameter than said cylindrical portion, the 50outer wall of said intermediate portion being threaded, the other end ofsaid body having a cylindrical outer surface of less diameter than thatof the externally threaded portion, said bore terminating at said otherend, said other 56 end having apertures therein, said body having arecess therein at the-extreme end thereof forming a tubular end, saidtubular end having a bevelled face, said recess including a cylindricalperipheral wall, said body having slots therein leading to said recess,and a hollow cap member including a cylindrical inner portion slidablyengaging the first mentioned cylindrical portion of said body, said capalso including an internally threaded portion engaging said externallythreaded portion of said body, said cap having a disbharge orifice inits lower end, said cap including a bevelled portion adjacent to saidorifice and having another bevel on its inner surface, the bevelled faceof said body engaging the last mentioned bevel on said cap. a
